SPECIFICATION forming part of Letters Patent No. 355,652, dated January 4, 1887.

7 Application filed October 1, 1886. Serial No. 215,085. (No model.)

To all whom it may concern;

Be it known that I, LINDEN KIRLIN, 'of Axtell, in the county of Marshall and State of Kansas, have invented a new and Improved Listed-Corn Cultivator, of which the following p is a full, clear, and exact description.

My invention relates to the construction of a novel form of listed-corn cultivator, wherein the parts are so arranged that two rows of corn may be cultivated at the same time; and the invention consists in the construction and arrangement of parts hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a plan viewof myimproved form of cultivator, the parts being shown in. the position they assume when the two horses attached to the evening-bar are abreast, the barrow attachment being shown in connection with one set only of the cultivator-blades. Fig. 2 is a rear view of the cultivator. Fig. 3 is a cross-sectional view taken on line a: acof Fig. 1. Fig. 4 is a diagram illustrating the position of the parts when one horse isin'ad: Vance of the other. Fig. 5 is a perspective view illustrating the construction of one of the brackets which serve to support the cultivating-blades; and Fig. 6 is an enlarged view of the bracket, representing the same as secured to the beam, which beam is shown in. section.

Referring now to the construction illustrated in the drawings, 10 10 represent two beams or blocks, to the under side of which there are secured brackets 11, said brackets being held to the beams by bolts 2, which pass through elongated slots 3', that are formed in the beams, so that the brackets of each beam may be adjusted toward or from each other. The aperture in the brackets 11, through whichthe outer bolt, 2, passes, is an elongated slot, as shown at 4 in Fig. 5. The brackets 11 are formed with arms 5, to which the cultivatorblades 12 are bolted, the apertures in'the arms 5 being elongated'to permit of a proper adjustment of the blades, these elongated apertures being shown at 7.

From the construction described it'will be seen that a perfect adjustment of the bladesend of the bar being secured to the beam or block'10 by a bolt, 15, while the rod or bar is held against a bracket, 17, by a bolt, 16, said bracket being formed with alongitudinal slot, through which the bolt 16 passes. The bracket 17 is held to the beam or block 10 by abolt, 6.

Each ofthe beams 10 .is connected to the bar 20, which answers the double purpose of an evener and draft-bar, connection between each beam and the bar 20 being establishedthrough the medium of chains 2L, that are secured to the beams and passed over sheaves or grooved wheels 22, that are mounted in proper bearings, 23, said bearings being secured to the bar 20. The two chains 21 are connected by a short rod, 24.. Properly-connected handles 30 are arranged as illustrated in the drawings.

Such being the general construction of the cultivator, the operation is as follows: A horse is hitched to each end of the bar 20, and the two sets of cultivator-blades are adjusted sov that the corn planted in the furrow will be within the opening between each set of blades. The blades are adjusted 'so that they will cut through the crust upon the side of the furrow, thus loosening and mellowing the ground-,and, although it is not absolutely necessary, I greatly prefer to arrange armsin connection with each cultivator-blade, as theteeth of such arms will act to thorough] y pnlverizeany clods of earth which may pass over the blades, and at the same time the teeth will prevent any heavy lumps of earth from falling upon the young plants. The bar 20, it will be 'understood, rests upon the tops of the ridges between the furrows, and from the peculiar connection between this bar andthe beams 10 the cultivatorblades attached to each beam will followin the furrow, even should one horse advance in front of the other. For instance,should the right-hand horse advance, the parts will as same the position in which they are shown in Fig. 4.

Eating thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a cultivator, the angle-bracket 11,

having a Hat upper arm provided with a transverse slot, 4:, near its onterend, and an aperture, as shown, and the lower arm, 5, extending downward and rearward from the .upper arm, and provided with two transverse the soil at opposite sides of arow of corn, substantially as shown and described.

3. The combination, with the two beams 10 10, each having a handle, 30, and two inclined rearwardly-diverging cultivatonblades, 1212, of the draftbar 20, having two pulleys, 23 23, near each end, and chains 2i, passed over said pulleys, and secured, respectively, at their ends to the beams 10 10 at opposite sides oftheir centers, substantially as set forth.

4. The combination, with a draft bar or evener provided with sheaves 22, of beams 10, carrying chains 21, which pass about the sheaves, links or bars 24, connecting the chains, and cultivatorblades and harrow-arms car ried by the beams, substantially as described.

5; The combination, with a beam, of brackets 11, adjustably connected thereto, cultivator-blades 12, adjustably connected to the brackets, and barrow-arms 14, that are connected to the beam and provided with harrowteeth, substantially as described.

LINDEN KIRLIN.
